Well there's six videos in that link you posted, so it's not clear the one you're referring to. Assuming it's this one, here's three big objections I have about it:

1. The routes certainly appear different on the go and return trips. It looks to me as though you're mostly staying on a large open road to benefit from tailwind, and then coming back on small narrow roads with trees/houses, shielded from the wind. Wind is why I use Champlain to return from downtown, but not to go there, at times there's no need to pedal! This effect can be pretty much neutered by doing a return trip using the same roads.

2. It looks as though you're pedaling for a good portion of that video, the way the camera bobs at a credible crank candece seems a dead giveaway. If the chain gets nuked for the video, then it can't be argued there's power input from there, no matter what.

3. We don't get to actually read the data on the meter. This makes the rest of the video rather pointless...

While it's easy for anyone with a speedometer to be misled about eff by having the wheel size slightly off, tracing the exact route on a map is pretty accurate. But, it would seem you've marked your starting about a mile off from Napili park, and you used different paths in the video...

You have to know, not fear, that someday you are going to die. Until you know that and embrace that, you are useless. - Tyler Durden, Fight club. Ditch the fake identity you've created for yourself, walk your own way in a society of mindless drones to become real, you are not your social status.

Doing the trip 1000s of times the numbers add up to the same average amp hours used at each voltage.The milage is always over 20 miles on the round trips regardless if I take the lower road for a couple of miles or cruise the beach along Kaanapali.Yes I do pedal some but it makes no difference in the little pedaling I do.Notice My videos are mostly over 1 hour for the 20 mile ride doing a leasurly ride mostly sitting streight up.I have noticed just ducking the wind gives me better performance than the hardest I can pedal on the whole trip.Still no one else even has a 20 mile video that even compares to my slowest one.Yes you can see when I ovivously pedal lightly for short periods.I never said that I didn't.
The 20 miles is from Napili Park to Lahaina Harbor and a few side excursions that add up to always over 20 miles.
For the worst performance climbing Haleakala Volcano to 10,005 feet in 36 miles with a 150 lb bike loaded with batteries the trip to the top drained a set of four 33 ah batteries at 48 volts.= 1584 watt hours or 48 watt hours per mile up hill but the down hill coast that took 40 minutes to get back down at 30 mph+ speeds the whole trip avraged 20 mph for 72 miles at 24 watt hours per mile carring 80 lbs of batteries.

Neither can we see your instruments or how you derive these specious numbers.

Match up any other 20 miles or longer ebike videos.There are None!
why is this? You would just prefer to fabricate trips with talk?

The sauce is just good magnets and a controller with right size rotor and stator to take less space and work efficiently for the power I use for long periods.There aren't many commercaily available with all of thses items.
I know what other motors perform like and how they are made to figure out what is now available and how other ebikes perform.I'm a thorne in here side when it comes to real long term tested facts. LoL.

Doing 1000s of miles on the same routes tells YOU something more than a few comments from people who have no idea yet...

Videos are just a great tool to see any! 20 mile trips averaging 20 mph or more and showing the batteries that were used.The smallest packs WIN! lol. Excepting claims has always been a problem since most claims are just claims wiith no videos of complete trips.Nice to amagine some of the figures that come up in these forums on graphs. lol
No guessing there!

Yes you may.That is about 20 miles on the highway in traffic of 55 mph most of the time with crazy drivers.So this is my route most times.http://www.gmap-pedometer.com/?r=794049http://www.gmap-pedometer.com/?r=794003
I like to do the coast as much as possiable which adds about 1 mile to the trip.Notice This was a regular type of town ride I do including crusing along the beach in front of the hotels and my slow speeds along the harbor and so on with stops and all my average trip was over 20 mph while my highway speeds were 30 to 45 mph most of the trip.Just the same two 7 lb li po packs is what I always carry now.The vally road to the north is great for testing up and down hills for averages in watt hours at different speeds and testing out ducking oposed to pedaling fast..Ducking always wins above 20 mph or into to a aparrent wind above 20 mph.I'm still waiting for other 1 hour videos. http://tinyurl.com/y5dgo5

And a certified calibration ? Yes Sir.Would you like GPS in view too? lol.I'm done with videos untill someone else produces one faster in a 20 mile round trip with less batteries.Pedaling or not... Try to maintain 20 mph for 20 miles on a 65 lb bike. Ebikes are ilegl here now.. Thats what this thread is about...

Randy's design looks very similar to the Voloci, only with pedals.
Pedals makes it legal almost everywhere. The Voloci was a very good design and worth duplicating.

Same thing occurred to me, in particular the arrangement of the seat tubes.
However the battery tub(ular frame) arrangement reminded me a little like the Powabyke or the Global Strong that CTC sells by the seashore.

There are many bicycle frames that will support a 5 lb motor with a 7 lb lithium pack for 30 mile ranges.A bicycle with a frame that supports four 7 lb packs will get you up to a 100 mile range per charge without pedaling, but not with a hub motor unless you pedal hard.I'm still waiting to see a hub motor ebike video with 20 mph average speed for 1 hour on a round trip with no pedaling using less tha 6 amp hours of battery power from 36 to 72 volts..http://video.google.com/videosearch?q=ecyclemaui

For ebikes that ARE the most EFFICIENT! the costs per mile can come down up to 20% per trip in the long run.Since No ebikes are yet Manufactured in the USA with Quality motors, controllers, batteries or Legal adjustability of power ranges by batteries alone there is much room for ebike improvements to start using expensive batteries.
A few improvement Ideas that seem to work well!http://video.google.com/videosearch?q=ecyclemaui

Tonight our Mayor came to the "Save Honolua" meeting. I had a chance to talk with her before the meeting begin about getting electric bikes legal again. She did not know they were illlegal and agreed it is a no brainer to get ebikes back on the road and in the DMV books.I was suprised she remembered my name after 8 years of not seeing her.. We also got 1 million from the county of Maui towards Honolua Bay open space funds to keep open space there and a coastal right of way acess. Now momentum on changing the ebike law will start.A non profit ebike rental with funds going towards a open space fund may be in order.
